Pure Python reimplementation of wireguard-tools with an aim to provide easily reusable library functions to handle reading and writing of WireGuard® configuration files as well as interacting with WireGuard devices, both in-kernel through the Netlink API and userspace implementations through the cross-platform UAPI API.
pipx install wireguard-tools
wg-py --helpImplemented wg command line functionality,
- show - Show configuration and device information
- showconf - Dump current device configuration
- set - Change current configuration, add/remove/change peers
- setconf - Apply configuration to device
- addconf - Append configuration to device
- syncconf - Synchronizes configuration with device
- genkey, genpsk, pubkey - Key generation
Also includes some wg-quick functions,
- up, down - Create and configure WireGuard device and interface
- save - Dump device and interface configuration
- strip - Filter wg-quick settings from configuration
Needs root (sudo) access to query and configure the WireGuard devices through
netlink. But root doesn't know about the currently active virtualenv, you may
have to pass the full path to the script in the virtualenv, or use
python3 -m wireguard_tools
sudo `which wg-py` showconf <interface>
sudo /path/to/venv/python3 -m wireguard_tools showconf <interface>The WireguardKey class will parse base64-encoded keys, the default base64 encoded string, but also an urlsafe base64 encoded variant. It also exposes both private key generating and public key deriving functions. Be sure to pass any base64 or hex encoded keys as 'str' and not 'bytes', otherwise it will assume the key was already decoded to its raw form.
from wireguard_tools import WireguardKey
private_key = WireguardKey.generate()
public_key = private_key.public_key()
# print base64 encoded key
print(public_key)
# print urlsafe encoded key
print(public_key.urlsafe)
# print hexadecimal encoded key
print(public_key.hex())The WireGuard configuration file is similar to, but not quite, the INI format because it has duplicate keys for both section names (i.e. [Peer]) as well as configuration keys within a section. According to the format description, AllowedIPs, Address, and DNS configuration keys 'may be specified multiple times'.
from wireguard_tools import WireguardConfig
with open("wg0.conf") as fh:
config = WireguardConfig.from_wgconfig(fh)Also supported are the "Friendly Tags" comments as introduced by
prometheus-wireguard-exporter, where a [Peer] section can contain
comments which add a user friendly description and/or additional attributes.
[Peer]
# friendly_name = Peer description for end users
# friendly_json = {"flat"="json", "dictionary"=1, "attribute"=2}
...
These will show up as additional friendly_name and friendly_json attributes
on the WireguardPeer object.
We can also serialize and deserialize from a simple dict-based format which uses only basic JSON datatypes and, as such, can be used to convert to various formats (i.e. json, yaml, toml, pickle) either to disk or to pass over a network.
from wireguard_tools import WireguardConfig
from pprint import pprint
dict_config = dict(
private_key="...",
peers=[
dict(
public_key="...",
preshared_key=None,
endpoint_host="remote_host",
endpoint_port=5120,
persistent_keepalive=30,
allowed_ips=["0.0.0.0/0"],
friendly_name="Awesome Peer",
),
],
)
config = WireguardConfig.from_dict(dict_config)
dict_config = config.asdict()
pprint(dict_config)Finally, there is a to_qrcode function that returns a segno.QRCode object
which contains the configuration. This can be printed and scanned with the
wireguard-android application. Careful with these because the QRcode exposes
an easily captured copy of the private key as part of the configuration file.
It is convenient, but definitely not secure.

config = WireguardConfig.from_dict(dict_config)
qr = config.to_qrcode()
qr.save("wgconfig.png")
qr.terminal(compact=True)from wireguard_tools import WireguardDevice
ifnames = [device.interface for device in WireguardDevice.list()]
device = WireguardDevice.get("wg0")
wgconfig = device.get_config()
device.set_config(wgconfig)The setconf/syncconf implementation is not quite correct. They currently use
the same underlying set of operations but netlink-api's set_config
implementation actually does something closer to syncconf, while the uapi-api
implementation matches setconf.
This implementation has only been tested on Linux where we've only actively used a subset of the available functionality, i.e. the common scenario is configuring an interface only once with just a single peer.
